I will always be a Rossi fan, and really enjoyed watching Sundays race, I was on the edge of my seat for the last 5 laps, I cant remember the last MOTOGP Race like that.
Regardless. if you like Rossi or not this season looks set to be a good one, I think Marquez was brilliant and see him winning the next race as they say its a Honda track and none of them have raced there yet.
just thinking on what you have said,I suppose its possible that in my case as the squish was very tight ( it almost cut through the solder I used) and there could be a small amount of movement on con rod, when the engine is hot and things have loosened up and expanded, the squish clearance would be vertually nothing and could cause the knock.It is a 95 engine so there must some wear. It sounds really good at the moment.
These are the only tyres, I doubt they are snow tyres as we just don't get enough snow - just a coincidence that there is snow in the pic. (I hope anyway!!!!)
Sorry, but I find it a bit hard to believe you would do all that work on an engine and not check the con rod for wear. I think probably any engine I have taken the top off I have had a look to see if there is any movement, also that you didnt check the squish clearance just out of curiosity before removing the head again. I don,t think you said what engine it was, but am assuming its 290 sherco, and I think probably the squish is more important on the larger capacity engines,
I had an SL for a few years back in the 80's, I had to keep welding patches on the exhaust were it rusted out, in the end there was more patch than original metal.
I wish now that I had taken photos of all the bikes that have past through my hands.
sorry I cant help with the magnet positions at the moment, but it does look the same as the TL set up I think I have got a spare I will try to have a look.
The advance unit does look different to mine (from memory, not seen it for a while) yours does look very dry, a bit of lubrication might help things move a little easier.
If you look on the forums,there are instructions on how to check squish with soft solder, its eay to do. I had issues with my gas gas when I bought it and the knock does sound quite serious, although there were no signs of the piston hitting the head there was almost no clearance, i fitted two base gaskets and took the clearance up to 1.5 mm, that was about three years ago, and its still fine.
hope this helps.
just remembered, rather than buy the gg gaskets I bought several sheets of different thickness gasket paper and made my own, much cheaper and easier to get the right thickness.

Yes . What Dom Said. He posted while I was writing.
Just a thought on your advance / retard unit, i had one from an xl engine and tried to use it, just because it looked newer than the TL one I was using, on close inspection the slot that lines up with the dowel on camshaft was in a different position and the springs and weights were different too.
So it may be that you need the camshaft and advance unit from a CT to make it all work properly with the CT stator..
Interesting about the stator / magnet positions being crucial, I supose it is not normaly some thing that crops up as its not usually variable.
Presumably the reason it worked ok with the battery set up is because you had a constant power at the coil/points.
Hope you get it sorted.

Just wanted to add, If the advance / retard is wrong it might rev if you raise revs slowly, but not under load or quick opening of throttle
well that sounds like a bit of mixture youve got there. Is the main engine TL.
I checked my TL yesterday and that has five wires coming out from the stator, I dont have lights so only use one wire.
I have an old stator that just has one coil inside ( off a TL125E) model and that is fitted to the bottom of the case.
I am not familiar with the CT as they didnt bring many of those into the UK.
I do know from experiance that the cam shafts for these engines are not all the same and are timed differently as are the centrafugal advance unit with the points cam on. You might have to ignore the marks stamped on the cam shaft sprocket and time it manualy.
I wouldnt think that the magnet positition would make any difference as it is not related to the timing like a bike with cdi ignition.
Back to the electrics, It does sound like a bad earth problem, Try running an earth cable to from engine to coil / condenser, if your frame has been painted or powder coated, this can cause a problem.,
I did have a TL125S model that was fully road legal (1978) and that had a battery fitted, maybe you could find a wiring diagram for that model.
One last thing, just thinking out loud really, I think they were wired with a constant charge to the battery via a regulator / rectifier and one of the stator wires went to the light switch so was only active when the head light was turned on and there was some thing electical mounted on the fork bottom yolk that pressumably took away the power at high revs to stop the bulb blowing.
I think we all tend to do that when out practicing, It helps if you can get a mate to set them out for you or with you, Include things that you dont like doing, so that you can practice those bits.
I dont like going over logs for some reason and you nearly always get them in our sections down in kent.
Turning on cambers is a good one to practice, make your section tight and keep at it, It does make you feel good when you do clean it.
Not today, but yesterday, Rode my Gasser in a great trial in kent. Mud, Mud and, more mud. Quite a few people had to take there front mudguards off so the wheel would go round.
Surely I can't be the only one that just Jet washs there bike off, quick wipe down,Wd - 40 over the moving bits and puts it away till next time.
I check it over the day before a trial, oil / adjust chain etc.
I have only had the stator cover of twice in three years, once just to have a look when I first bought it and once to replace crank seal. Both times it was dusty dry in there. 1995 gasser 350.
